First, rename and make that function static because it is internal to
control.c and called by two HS_DESC events.
Second, make it take more basic parameters and thus not a rend_data_t object
so we can still use the function for v3 HS that doesn't use that object.
Third, move the descriptor ID lookup to the two specific events (yes little
code duplication there) because they get a rend_data_t object which won't be
the case for v3.
Finally, through this refactoring, change the pointer check to BUG() and
change some parameter names to reflect what they really are.
No behavior change at this commit.

This is a naming refactor mostly _except_ for a the events' function that take
a rend_data_t which will require much more refactoring.
No behavior change at this commit, cleanup and renaming stuff to not be only
v2 specific.

When an intro circuit has closed, do not warn anymore when we can't find the
service. It is possible to hit that condition if the service is removed before
the circuits were fully closed. This happens in the case of deleting an
ephemeral service.

The functions are now used by the ADD_ONION/DEL_ONION control port command as
well. This commits makes them fully functionnal with hidden service v3.

Instead of using the cwd to specify the location of Cargo.toml, we
use the --manifest-path option to specify its location explicitly.
This works around the bug that isis diagnosed on our jenkins builds.
Making errno error log more useful for getrandom() call. Adding if statement to
make difference between ENOSYS and other errors.

First, hs_service_intro_circ_has_closed() is now called in circuit_mark_for
close() because the HS subsystem needs to learn when an intro point is
actually not established anymore as soon as possible. There is a time window
between a close and a free.
Second, when we mark for close, we also remove it from the circuitmap because
between the close and the free, a service can launch an new circuit to that
same intro point and thus register it which only succeeds if the intro point
authentication key is not already in the map.
However, we still do a remove from the circuitmap in circuit_free() in order
to also cleanup the circuit if it wasn't marked for close prior to the free.

The hs_service_intro_circ_has_closed() was removing intro point objects if too
many retries.
We shouldn't cleanup those objects in that function at all but rather let
cleanup_intro_points() do its job and clean it properly.
This was causing an issue in #23603.
Furthermore, this moves the logic of remembering failing intro points in the
cleanup_intro_points() function which should really be the only function to
know when to cleanup and thus when an introduction point should be remembered
as a failed one.

In the KIST main loop, if the channel happens to be not opened, set its state
to IDLE so we can release it properly later on. Prior to this fix, the channel
was in PENDING state, removed from the channel pending list and then kept in
that state because it is not opened.
This bug was introduced in commit dcabf801e5 for
which we made the scheduler loop not consider unopened channel.
This has no consequences on tor except for an annoying but harmless BUG()
warning.

Some platforms don't have good monotonic time support so don't warn when the
diff between the last run of the scheduler time and now is negative. The
scheduler recovers properly from this so no need to be noisy.

When creating a routerstatus (vote) from a routerinfo (descriptor),
set the IPv6 address to the unspecified IPv6 address, and explicitly
initialise the port to zero.
Also clarify the documentation for the function.
Fixes bug 24488; bugfix on 0.2.4.1-alpha.
